application sied-inruil 26,1907. seni-.1 No. 364.689.

To all whom it may concern:

of the boiler by'a pipe 15 having a hand-controlled B e it known that I, Jonas A. KBETZER, a citizen valve 16, whereby the supply of steam 'to the device of the United States, residing at MoundCity, in the county of Holt and State of Missouri, have invented new and useful Improvements in Steam Ash-Removers for Boilers, of which' the following is a specification.

This invention relates to boiler appliances and relates more particularly to a device for removing the ashes from th boiler furnace by means of the inject- I ing action of a jet of steam directed into a suitably arranged conveyer or duct.

The invention has for one ofV its objects to improve can be opened or closed and regulated.

By opening the valve-16, a powerful jet of steamis discharged through the duct 6 so that as the ashes and Vcinders drop through the grate during the cleaning of the fire, they will be sucked through the duct by the steamand discharged therefrom, thus relieving the fireman of the necessity of manuallydisposing ofthe ashes.

and simplify the constructionand operation of apparatus of this character so as to be comparatively easyl and inexpensive to manufacture, composed of few parts, easy to manipulate, and thoroughly effective in use. v

A further object of the invention is the provision of an ash and cinder collecting means disposed below the boiler grate and provided withan outwardly discharging duct having a `deflector at its outer end for discharging the ashes and cinders in any desired direction. y

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter, and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one of the embodiments of the invention, Figure l is a transverse section of a boiler and of the ash-removing device, the discharge duct of the latter having an intermediate portion broken away.' Fig. 2 is a horizontal section on line 2-2,' Fig. 1. Fig. 3 is a perspective view of the hood or deflector fo'r directing the ashes and cinders discharged from the duct. Fig. 4 is a transverse section on line 4 4, -Figl 2.

Similar reference characters are employed to designate similar parts throughout the several views.

Referring, to the drawing, 1 designates a fire tube boiler of any approved construction having the usual masonry setting 2 and a firebox 3 and ash-pit 4. One of the walls of the setting has an opening 5 through which the discharge duct or pipe 6 of the ash remover extends. Under the grate 7 is a collecting chamber 8 having a hopper 9 whereby the ashes and cinders are directed from the grate to the chamber 8, there being an inclined plate 10 in the chamber which 'assists in directingthe ashes and cinders into the mouth or funnel 1]. of the duct 6. Arranged in laxial alinement with the duct, which latter may be of any desired length and diameter, is a steam discharging nozzle 12 cnnected with a pipe 13 extending horizontally through one wall of the boiler setting and through the inclined plate 10. This pipe is connected with the dome 14 On the outer end of the duct 6 is arranged a device for directing the stream ofashes and cinders in any desired direction' so as to prevent a pile being deposited directly at the end of the duct and interfering with its successful operation. This device comprises a scoopshaped delector or hood 17 pivotally mounted at 18 so as to be adjusted to either the dotted or fullline position shown in Fig. 2, whereby the ashes and cinders may be deflected to the right or the left. The hood is pivoted on a frame composed of top and bottom members 19 arranged exterior to the duct 6 and pivoted at 20 to a split clamping ring 21 encircling the duct 6. Connected with each member-l9 at an intermediate point thereof is a semi-circular strip 22 that serves as a stop adapted to engage the duct and hold the hood in a central position. By pivotally mounting the members 19, the hood can be'thrown to one side and ont of line with the duct so that the ashes and cinders will discharge in a straight line outwardly from the latter. After a pile has.l been thus produced, the hood supporting' frame can be thrown back to the full line position, Fig. 2, whereby the ashes are thrown laterally to'one side or the other according to lthe adjustment of the hood.

, From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the methods of operation will be readily apparent by those skilled in the art to which the invention appertains, and while yI have described the principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative land that such changes may be made when desired as are `within the scope of the claims.

Having thus described the invention, what I claim isz- 1. In an apparatus of the class described, the combintion of a iirebox including a grate, a collecting chamber below the grate, a hopper between the chamber and grate, a. duct leading from the chamber, an inclined plate for directing the ashes and cinders into the duct, a steam discharging pipe extending through and supported on the inclined plat'e and arranged in axial alinement with the duct, and a deecting device at the outer end of the duct.

2. 1n an apparatus of the class described, the combination of' a furnace having an opening in one wall communicating with the ash pit, a grate, an inclinedfplate in theV ash pit arranged to direct the ashes from the grate to the opening, a steam discharging pipe passing horizontally through and supported on the' wail opposite from that having the opening and arranged with its discharge end ezxtendinglthrough the Vinclined plate and located centrally in line with the opening, a horizontal duct secured in the opening for receiving the ashes ejected by the jetfof steam discharged from the pipe, and a deecting device mounted on the outer end of the duct to be 'turned thereon and including an adjustable hood for deecting the material to one side or the other. l

3. In an apparatus of the class described, ythe combina- 'tion ot a furnace, a duct leading from the ash box thereof,

means for ejecting the` ashes through the duct, and -a debars, and a member connected with the bars at a point in- 20 4termediate the ring and hood for engagement with the outside of the duct to hold the deecting device in proper relanon Ito the duct.

In testimony whereof, I aliix my signature in presence of two witnesses.
